Bright Band of Transformation

One of the guests at Rylan's birthday party is a family friend named Bill.  Bill and Keith were pilots together years ago and still fly together for fun.  On the drive down to the party the clouds were gorgeous.  I can't pass up the opportunity of two professeional pilots in the car (plus Mary who used to fly).  I pepper them with questions and hear  horrifying  weather stories. 

When we start talking about radar, Bill tells another scary story where he was flying into a storm and radar saved him.  When the control towers only had radar, the Bright Band was the only way to tell when the weather was changing from rain to ice. That moment when water stops being rain and becomes ice literally shows up on radar as a bright band.  The Bright Band of Transformation.
